Backup cam + Road runner help

Hey all, I have a 3com home connect USB webcam I plan to use as a backup cam. I am using Road Runner front end. For some reason, I can't get the Winamp TV plugin to reconize my camera.

In the Video tab, it sees the driver for it. Then, when I go to "Add Manually" my camera, in the "Other inputs" drop down menu, all that shows is "Default". For some reason, it's not seeing my camera. All drivers are installed correctly along with Road Runner and Winamp and plugins.

Any suggestions? Also, I don't know what "WDM" means in the FAQ on this subject. What's it mean to have a "WDM Webcam"?
